MUMMALS: multiple sequence alignment improved by using hidden Markov models with local structural information

Jimin Pei and Nick V. Grishin

The authors would like to apologize for the following statement in Results:

PREFAB4 consists of 1682 alignments based on the consensus of two structural alignment programs SOFI (40) and CE (41), with up to 24 homologous sequences added from database searches.

The correct statement should be:

PREFAB4 consists of 1682 alignments based on the consensus of FSSP and CE alignments, with up to 48 homologous sequences added from database searches.
